TUBE-MAKING MACHINE.

SPECIFICATION formingpart of Letters Patent N 0. 710,507, dated October 7, 1902.

Application filed March 19, 1902. Serial No- 98,918. (No model.)

To all whomit may concern:

Be it known that I, FRANCIS O. OSBORN, a citizen of the United States, residing at 2'2 Putnam avenue, in the city of Detroit, county of Wayne, and State of Michigan, have invented certain new and useful Improvements in Tube-Making Machines, of which the following is a specification.

This invention relates to improvements in machines for manufacturing continuous spirally-wound tubing of paper or other material, and more specifically to that class of machines in which the strips of material are carried spirally around a stationary mandrel and moved continuously forward toward the end of the mandrel by a belt or belts wrapped about the material and mandrel and driven in the proper direction and at the proper angle to wind the strips into a tube in which the strips may be joined either with overlapping or abutting edges and with the layers arranged with broken joints.

My improvements consist in an improved driving mechanism and other improvements, all of which will be more specifically pointed out in the claims.

In the drawings, Figure 1 is a plan view of the machine. Fig. 2 is a top View of mandrel, strips of material, and belt. Fig. 3 shows paste apparatus in section. Fig. 4c is a belt-driving pulleyin side elevation, showing gearing and belt-tightener slide. Fig. 5 is a belt-driving pulley in elevation, showing gearing and connection with main shaft; Fig. 6, a top View of Fig. 5. Fig. 7 shows beltguide.

The mechanism is mounted upon a base or bed A similar to a lathebed. The main driving-shaft B is mounted in brackets 19 at one side of the base and may be driven by a large pulley mounted directly upon it or by a smaller pulley and gearing, as shown in the drawings, in which the power is transmitted from the cone-pulley (3 through the back gearing and the intermediate gear to the shaft, as is clearly shown in Fig. 1. The mandrel M, held in a fixed position by inserting one end in a socket of the headpiece of the bed, is mounted centrally on the bed and sufficiently far above it to bring it in the horizontal plane of the belt-driving pulleys p p.

The belt-driving pulleys p p of which there maybe one or more pairs, are keyed upon vertical stud-shafts s, mounted in bracketbearings s. The lower ends of these studshafts are fitted with bevel-gears G, arranged to mesh with bevel-gears g 9' The gear g on the side on which the main driving-shaft B is located is mounted on the driving-shaft and is driven thereby. The bevel-gear g on the opposite side of the machine is driven by a shaft 5 mounted on the swinging bed-piece S anddriven through the gear g, meshing with the gear G. The number of teeth ofthese several gears is such that the beltdriving pulleys are all driven at the same speed. A sliding bed-piece S is arranged to be moved along the ways of the bed, and upon this is mounted a swinging bed-piece S, pivoted to the sliding bed-piece at or near its center. The swinging bed-piece carries the pulleys, stud-shafts, and gearing described above. One of the belt-driven pulleys of each pair (preferably the one on the side opposite the main driving-shaft) is mounted on a slide arranged in the usual manner, with screw and hand-wheel for moving the same for the purpose of changing the distance between the pulleys in order to give proper tension to the belt. (See Figs. 1 and 4:.) The main drivingshaft, in addition to the fixed bearings b, has a swinging bearing b mounted on each of the swinging bed-pieces S. This bearing consists of a bracket-piece pivoted to the swinging bed-piece S, so that it swings concentrically with stud-shaft above it. (See Fig. 5.) The gear g is sleeved in the bearing and is held therein by a collar 0 threaded on the sleeve. The shaft passes through the gear and sleeve and has spline-and-groove connection therewith. The gear g also has spline-and-groove connection with the shaft 5 The main shaft is provided with the universal joints J, which permit it to adapt itself to the varying position of the bearings Z) when the swinging bed-pieces are moved to change the angle between them and the mandrel. An endless belt T is provided for each pair of pulleys and is mounted thereon, as shown in the drawings, with one turn around the mandrel. Thebeltsshouldbe aboutthesame width as the strips of material to be wound. One strip of the paper or other material to be wound is fedto the mandrel dry, as shown at 1. A second strip 2 is fed from the opposite side of the mandrel and provided with paste on one side. The paste may be applied in any suitable manner. The apparatus for applying the paste shown in the drawings consists of a box 11, in which is mounted a roller 0', having suitable bearings and provided with a pulley 11 which is connected by belt to a pulley n on the main shaft. The paper strip is guided over the roller, carrying the paste under a guide-roll if, over a scraper U5, and under second guide-roll 0 A hopper '0 is provided for convenience in supplying the box with paste, and the roll of paper or other material is mounted above the box in suitable brackets.

The strips of material are carefully guided at the point where they pass onto the mandrel by adjustable guides 93 m, which are slid ably connected to the bed at 00 The strips are further guided and forced forward along the mandrel by the extended guide-pieces z z. Strip 1 is thus guided by the piece .2, fast on the mandrel, and strip 2 is guided by piece z, extending over the surface of the mandrel from the adjustable guide 9;.

A third and fourth strip of material may be wound in a manner similar to the winding of strips 1 and 2, in which case similar guides, paste, rolls, &c., would be provided and arranged in connection withthe second winding-belt. In this case both the additional strips would need to be provided with paste. It will be obvious that by increasing the number of winding-belts any number of strips may be wound into one tube in this manner.

It being understood that the swinging bedpieces S are notat all times in parallel relation with only two sets of pulleys and two swinging bed-pieces, as shown in the drawings, it is necessary to employ only two universal joints in the driving-shaft. If additional sets of pulleys mounted on independent swinging bed-pieces are used, a universal joint in the shaft for each of such swinging bedpieces would be necessary and would be located in the portion of the driving-shaft connecting the bed-pieces shown with such additional bed-pieces.

What I claim is 1. In a tube-forming machine, a mandrel, a continuous winding-belt passing to, over, and around the mandrel, a pair of pulleys for driving the belt mounted upon a swinging element, a main driving-pulley, and a flexible driving-shaft connection between the main driving-pulley and the belt-driving pulleys, substantially as set forth.

2. In a tube-forming machine, a mandrel, a continuous winding-belt passing to, over, and around the mandrel, a pair of pulleys, one on either side of the mandrel, for driving the belt, a swinging bed-piece carrying the pulleys whereby the angle between the mandrel and belt may be varied, a main drivingpulley mounted upon the fixed framework of the machine, and a universally-jointed connecting-shaft between the main pulley and the belt-driving pulleys, substantially as set forth.

3. In a tube-forming machine, a mandrel, a continuous winding-belt passing to, over, and around the mandrel, a pair of pulleys, one on either side of the mandrel, for driving the belt, a centrally-pivoted swinging bedpiece carrying the pulleys whereby the angle between the mandrel and belt may be varied, a main driving-pulley mounted upon the fixed framework of the machine, and a universallyjointed connecting-shaft between the main pulley and the belt-driving pulleys, substantially as set forth.
